To @ZZ 107mm it' muy concern: r

, lie it known that I, JAMES RELIGHA. NEIL- sON, ofDelamar', in the county of Lincoln and State of Nevada, have invented a new and Improved Straightening and Drilling Machine, ofwhich the following is a full, clear,A

and exact description.

'lhe object ol' the invention is to provide a new and improved straightening and drilling machine for .straightening rails, axles, pipes,

and the like and for drilling holes in various` articles-for instance, in rails for fish-plate bolts-the machine being sim ple and durable in construction,,readily applied, and easily and con vcniently manipulated to laccomplish the desired result Without undue exertion onthc part of the operator.

The invention consists of novel features and parts and combinations of the same, as'

will be l'ully described hereinafter and then pointed out in the claims.

A practical embodiment of my invention is represented in the accompanying drawings,

forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a plan view of the improvement with parts in section. side elevation of the same, on the line 22 in Fig. l. Fig. l is a reduced side elevation of the improvementarranged as v'a drilling-inachine. Fig. 4 is a side elevation of the drillrod. Fig. 5 is a side elevation ol the ratchetdrill, and Fig. (i is an enlarged side elevation of one of the frame ends designed for engaging pipes and axles. 1

'lhc improved machine is provided with a iranie Apiiproximately U-shapcd and formed at the ends A to readily engage and hold the article to be supported or drilled. For instance, as shown in Figs. l and 2, the ends A are formed with spaced lugs l'or engaging the side edges of the base of a rail l'. (indicated in Fig. i2.) Between the ends A is arranged a head C on a straightening-bar C, mounted to slide in the end barA2 of the frame A and in a connecting. or cross bar A, the said head U' being adapted to engage the rail approximately niidway between the ends A; The

head C' is so shaped as to engage the rail ol'- other article eitvher on one side or the other, so .-is to either push the rail into :t straight Fig. 2 is a sectional forni or pull it into the desired'shape, as the case may be. The outer end C2 of the bar C is threaded and is engaged by a nut D of. a ratchet-drill D of any approved construction 'and held against longitudinal movement on the bar C by being litted between lugs A4 on the frame-bars A.2 A. A holder E loosely engages the side bars of the frame A, and in the holder is also fitted to slide the bar C, so that the latter is prevented from turning, and at the same time the sides ol' the frame Aare prevented from spreadingwhcn the device is used for straightening an article. New it is evident that when the machine is applied and the usual motion given to the ratchetdrill D then a sliding motion is given to the rod C, so as teinove the saine in the desired direction to straighten that portion of the rail B or other article extending between the ends A ofthe traine.

The barC is made hollow to permit the insertion of a drill-rod F, (see Figs. I3 and 4,) the drill-rod being provided at one end with a socket F for receiving the drill G, and the other end is adapted to receive a second drill Il, similar to the ratchet-drill D, and serving to turn the rod F for drilling the hole, While the feeding is done by actuating the ratchetvdrill D to slide the bar C in the desired direction. It is understood that the socket F is engaged by the outer or head end oi' the bar C, so that when the latter is moved outward upon the operator manipulating the ratchetdrill D then the rod is carried along, and as the rod is turned at the saine time it is evident that the drill will drill a hele in the article.

As shown in Fig. 6, the end Af' of the frame A is shaped to more readily conform to the cross-section ol' a pipeor an axle to allow of using the machine on suchy articles.

Having thus fully described my invention, l claim new and desire to secure bylietters latent-- l. ln a device of the class described, the combination with an approximately U-shaped l'ramc having ends for engaging an article at spaced points, of a tubular bar slidable in said frame at a point about midway between the l'ranle ends, thesaid tubular bar being led at one end, a i-'atehet-\\'heel on the thrrmded rnd ol' said lnrrnnd held against lon- ICO gitndinal movement in said frame, a helder engaging the frame ends and the said bar to preventtlie latter from turning and the ends of the 'frame 'from Spreading, and a drill mounted to turn in the said inbnlar bar and arranged 15oV be moved longitudinally by miie movement of said tubular bar, substantially as deseribed.

2. In a device of the class leser-ined, die eem binatien with an approxin'niiiely U -Sliaped frame having ends for engaging an ariliele at spaced points, of a isnlnxlar bar slidablo in said frame, die said bar being threaded at one end, a ratchet-wheel en the threaded end of the said bar and held against longitudinal movement in .the lraine, means ler wgeraingr the ratchet-wheel,valiolderengagingthe i'ranie ends and the said liar to prevent the latter 'from turning and the ends of ille frame from Spreading, a drill-rod movable in said inlanlar bar and provided at one end with a socket adapted to carry a drill, the end of Said inbnlar bar being adapted io engage the said sockel', and a seeond ratchet-wheel engaging Said drill-rod for turning.; ity in inne iinlinlar liar 'z Y Y efieywe at ille ime the latlter'is moved' bodily in the frame by aetiiiabing ilie first-named ratchetvfiieel, substantially as shown and describedt The combination with an approximately ill-shaped frame having side bars formed at their ends te engage and hold an article, a. top er end bar connecting the side bars, and across-bar connecting the side bars below the iop or end bar, of a inbular oar slidable in the rop er end bar of thel frame and in said Cross-bar, rile said tubular bar being threaded at one ond and arranged to receive a drillingroel,1 a device engaging the threaded portion of the Lnonlar bar for moving the saine longitniiinally, the Said device being located isei'ween the Een er end bar of the frame and the Cross-barand heid against longitudinal nieveinen, and a. helder engaging the Side bars of the frame and Lne said rnbnlar bar to prevent llxe latter from turning and ialie bars from spreading', substantially as described. i
